4054 DynamicSignals Recording Datalogger CAMAC Module

The 4054 is a high-capacity memory module with memory size options of one, two, or four megasamples. Up to four 4054s can be connected to one datalogging recorder, giving a total memory capacity of sixteen megasamples. When more than one 4054 module is used, each must have four megasample capacity. The available memory per channel is the total memory divided by the number of active channels. For smaller memory requirements, a 4050 memory module may be substituted for the 4054. However, 4050 and 4054 modules may not be used together in a system.

The input signal for all channels is received on two 34-contact ribbon connectors. Sample rate is controlled by a programmable internal clock that is selectable from 0.1 hertz to 5 kilohertz or by an external TTL-level clock. A clock-out signal is provided for driving another recording datalogger.

The samples for each channel can be read out contiguously by an F(2)•A(0)command [preceded by an F(17)•A(0) channel command]. The readout can also occur in a streaming fashion (channel data interleaved) by using the F(2)•A(1)command. Both single-channel and streaming readout can be at full Dataway speed.

As an aid in system setup, the ADC can be read directly: “present value monitoring” Read commands are included. Each 4024 contains a 32-word memory, readable from the Dataway with an F(1)•A(0) for single-channel or an F(1)•A(1) for reading all 32 channels. The F(17)•A(1) command is used to select the starting channel (1-32). This feature is also useful for applications where a 4054 memory module is not needed. The 4024 can then sample 4, 8, 16, or 32 channels once, and store the conversions in the 32-word memory.
